+TraCI stands for Traffic Control Interface, a protocol that defines messages that can be used to control a traffic simulation that runs in client-server mode. 
+
+Communication uses TCP messages with the following structure:
+{{{
++--------------------------+-----------+-----------+-----+-----------+
+| message length (4 bytes) | command_1 | command_2 | ... | command_n |
++--------------------------+-----------+-----------+-----+-----------+
+}}}
+
+A command contains the following:
+{{{
++-----------------+---------------------+---------+
+| length (1 byte) | identifier (1 byte) | content |
++-----------------+---------------------+---------+
+}}}
+or, for longer commands
+{{{
++------------+------------------+---------------------+---------+
+| 0 (1 byte) | length (4 bytes) | identifier (1 byte) | content |
++------------+------------------+---------------------+---------+
+}}}
+
+The server will reply with a single message contaning the responses to every command received, in the same order.
